Had a version of this after a major Flemmings feast
After way too much of Flemmings potatoes this is nice
Also budget and fat friendly
5 cups water
2 cups sugar
3 Tbs finely chopped ginger root
2 tsp finely grated lemon zest
2 tsp finely grated lime zest
3 Tbs fresh lemon juice
3 Tbs frsh lime juice
mint leaves for garnish
Combine water, sugar and ginger in saucepan. Bring to boil stirring until sugar dissolves. Reduce heat and simmer 10 minutes. Strain liquid into large bowl and discard ginger.
Return liquid to saucepan, add lemon and lime zest. Boil 2 minutes. Whisk in lemon and lime juices. Allow to cool completely. Pour mixture into 13x9 glass dish. Cover and freeze over night.
Transfer mixture to a processer and puree until smooth. I found a dough hook worked well for this. Return to glass dish and freeze until solid, at least 3 hours. Scoop Sorbet into bowls and garnish with mint.
